基于FSM检测的移动自组网攻击分类研究

在移动自组网环境下,由于移动节点可能被攻击截获,导致攻击从内部产生,传统的网络安全措施难以应用,只有通过入侵检测才能发现攻击者。通过分析移动自组网的攻击类型,并构造从恶意节点发起的攻击树,采用有限状态机的思想,设计一个基于FSM的入侵检测算法。采用该算法的入侵检测系统可通过邻居节点的监视,实时地检测到节点的各种攻击行为。

Attack Classification for Ad Hoc Network Based on FSM Detection System

In mobile Ad Hoc network environment,it is likely to bring more attacks from the node interior because the mobile node is very easy to be attacked.Therefore,the traditional network security mechanisms are difficult to be applied,and only the intrusion detection system can find the attackers.The types of attacks on MANET is analyzed,and then an attack tree launching from a malicious mobile node is constructed.An intrusion detection algorithm based on FSM is designed with the idea of finite state machine.The IDS with the algorithm can detect various attack behaviors of the nodes on real-time by monitoring the neighbor nodes.
